HydroCAD Supports
Prinsco Stormwater Storage Solutions
HydroCAD provides full support for the stormwater storage products offered by Prinsco, Inc. including HydroStor® stormwater chambers and all dual-wall pipe products including GoldFlo®, GoldFlo WT®, EcoFlo 100® and GoldPro Storm.
This
partnership allows Prinsco products to be easily used within any HydroCAD model
for stormwater storage, detention, or infiltration. HydroCAD includes
complete Prinsco storage definitions, plus an interactive chamber
wizard for easy layout, pricing, and modeling of
underground storage systems.
Prinsco pipe products are supported in HydroCAD-10 "build 4", with the latest "v2" storage data added in HydroCAD 10.20-7a. Prinsco chamber products (including the HS31, HS75, HS180, and HS290) are supported in HydroCAD-10.1 release 6, although 10.20-7a is required for the latest "v3" chamber data. Details here.
How storage is modeled
Stormwater storage typically appears in a HydroCAD model as part of the storage definition for a "pond". In the simplest case, HydroCAD calculates the total available storage, including the interior of the chambers (pipes), plus the void space in any surrounding stone. For a more complete analysis, a full stage-storage curve is calculated so that an inflow or runoff hydrograph can be routed through the pond. The resulting analysis indicates the water levels attained throughout the rainfall event, as well as any discharge that may occur through outlet devices or infiltration into the surrounding ground.
Flexible storage options
Each HydroCAD pond may include an unlimited number of storage definitions as required to describe its overall storage characteristics. This makes it easy to model complex storage arrangements, such as a combination of multiple chambers, catch basins, or other contributing volumes.
But the most significant feature is the ability to embed (bury) chambers in a bed of stone, and have HydroCAD automatically calculate the combined storage at any water surface elevation. This makes it easy to determine the storage for virtually any configuration of storage chambers, without resorting to any manual calculations.
HydroCAD can also model almost any imaginable storage arrangement, including
layered chambers of different sizes combined with auxiliary storage from
adjacent pipes and catch basins, and even the above-ground areas (parking lot)
that may provide overflow storage for certain events.
Using Prinsco stormwater products
Setting up a pond to use Prinsco chambers or pipe storage is a simple process: Just pick the desired product and size from the drop-down lists, and specify the number of chambers (pipe lengths) plus their elevation. The HydroCAD chamber wizard automatically calculates the overall size of the system based on the manufacturer's recommendations, or you can customize the layout to suit your specific requirements.
Technical notes
The HydroCAD
definitions for Prinsco dual-wall pipe are based on the actual inside diameter and
displacement as listed here.
